1、查看数据库的运行模式

C:Documents and SettingsAdministrator>sqlplus? sys/admin@orcl as sysdba;

SQL>archive log list;?????????????? --(查看数据库的归档模式)

如果是noarchivelog，进行下面步骤：

SQL>shutdown immediate;

SQL>startup mount;

SQL>alter database archivelog;

SQL>alter database open;

2、连接到RMAN

C:Documents and SettingsAdministrator>rman nocatalog target sys/admin@orcl;

3、对数据做一次全备

RMAN>backup database format 'e:\temp_%U';

4、关闭数据库，删除所有的数据文件，模拟数据库损坏文件丢失现象

RMAN>shutdown immediate;

RMAN>startup mount;

RMAN>restore database;

RMAN>recover database;

RMAN>alter database open;

5、RMAN基本设置

RMAN>configure dafault device type to?disk;(设置默认的备份设备为磁盘)

RMAN>configure device type disk parallelism 2;(设置备份的并行级别，通道数 )

RMAN>configure channel 1 device type disk format 'e:\backup1\backup_%U';
